Other objects and 'advntages 'ofthe invention Wllbe pointed outin the A'following `dr'etailedide-- scription of an illustrative embodiment ofthe vention shown in the accompanyihg'dfavviiigsfin which:

"Fig 3 is a section of the` neck portion of the closure on the line 3-3 of Fig. 1 and Fig. 4 is a central section of the closure :showing the cap portion seated in the 'neck portion.

Referring@ the drawings, lis s lianes shown integral with the neck portion 'of 'the closure.'

The vflange is provided for securing the closureV to the wall or surface of the `structure surroun'df ing the opening to be closed such a'sfor example the Wall oi a liquid fuel tank or an airplane 'vvingI .the internal rounded sealing bead 3. Adjacent its lower edge the neck is provided'u/ith the inwrdly' extending flange 4 which provides 'a seat for `the spider member of the cap portion of the closure.

Extending downwardly from the flange l fis a eyiindricai skirt 5 the ioweif edge of which is cut or'shaped to provide 'a plurality of com surfaces 6 (three illustrated) `evenly distributed around the circumference of the skirt.. The flange 4 and skirt 5 are completely cut vavvayfat three points to .provide Vslots 1 for the passage of the dog members of thecap. i

'I'he cap portion of the closure comprises the disc 8, the top `or outer surface of which may be yof any desired shape but preferably is .dat

or curved to conform to the contour of the surf rounding surfoce. Extending downwardlyl `from the disc 8 is the Cylindrical wall or skirt 9 p'ovided with. the external. groove 'l0 4which ons provide a closure 'in vvhich packing *not subjecteed.te` rubbing friction in the insertion and removalof' tains the packing ring Il. The packing ring H may be circular in cross-section and formed of rubber or other suitable deformable packing material and preferably, as illustrated, is of less diameter than the vertical dimension of the groove I so that it may roll slightly in the groove. This facilitates the insertion of cap in the neck in that it permits the packing to roll instead of slide over the bead 3. The packing must of course have a greater diameter than the depth of the groove I0 so as to engage the bead 3.

Extending downwardly from wall 9 are the three fingers I2 at the lowerfends of whichare the outwardly extending dogs I3 which pass through the slots 1 and engage the cams 5.

The disc 8 also has at its center the downwardly extending cylindrical shaft or stud I4 which carries the spider I pressed downwardly by the spring I3 and retained by the pin I'I. A washer I8 is inserted between the spring IS and the Spider I5 to facilitate relative rotation. The spider I5 is a circular disc of a size to rest on the iiange 4 with portions cut away as indicated at yI9 to permit relativel rotary movement of the fingers I2. If desired, means (not shown) such as acam on the lower surface of the spider I5 may be provided to straddle the retaining pin I'I and retain theI spider I5 in the desired alinernent with the fingers I2 so that after the cap is ,inserted in the neck the cap may be rotated to engage'the dogs I3 `with the cams 6 without rotation of the spider, i. e. so'that the fingers I2V andv dogs yI3 move within the cut away portions I9 of the spider. This is not essential because the spider I5 may be rotated with the cap but its contact with the flange d and the pressure of the spring IS causes it to offer considerable frictional -resistance to rotational movement. It is noted that the legs of the spider are of sufficient width that they will not fall into or pass through the slots I. l

Means (not shown) such as a chain, cable or (coil spring may be providedwith one end attached to the stud I4 and the other end attached :to the skirt 5 for preventing complete detachment and loss of the cap portion of the closure.

In operation the spider preferably is positioned on the cap with the counter-clockwise edges of the cut away portions in contact or substantially in contactwith the fingers I2. The cap is then inserted in the neck. Since the dogs I3 extend slightly below the spider I5 it is easy to feelfor the slots 1 by means of the dogs. As the cap enters the neck the spider I5 engages the fia-nge Il before the packing ring II engages the bead 3.

The cap is then pushed downwardly compressing the spring IB. This downward movement brings the dogs I3 below the level ofthe cams E Vand: also forces the packing ring II past the bead 3. The cap is then rotated to bring the dogs I3 under the cams 6 and released whereupon the pressure of the spring I6 downwardly against the spider I5 resting on the flange A and upwardly against the disc 8 raises the cap until the dogs I3 engagethe cams 5. The dimensions of the parts are such that when the dogs i3 are seated on the cam surfaces the disc 8 lies flush with the upper edge forced'upwardlyrby the spring I6 to a positionA where it can be grasped by the fingers and re-' moved from the neck.

As will be apparent neither the rotation of the cap clockwise in inserting it nor the rotation counter-clockwise in removing it involves any considerable amount of friction because in these operations the only frictional `contact is between the'spring 16' and the washer I8, the dogs I3 being clear of the cam surfaces 6 and the packing ring II being clear of the bead 3 and there being no relative movement between the spider I5 and the iiange 4. Consequently, the cap may be inserted and removed by simply pressing the l bead andcam surfaces respectively of said hand against thefiat smooth surface of the cap and no handle or tool is required.

t The inclined cam surfaces and the spring tension prevent accidental rotary movement of the cap to its released position and tend to hold the cap in its fully engagedfposition. If, when the cap is inserted, it is not rotatedto fully engaged position it will tend tofseek this position rather than to seek the released position.

yIt will be noted'I thatv there is very little spacev between the packing `ring and the surface ofthe cap for the accumulation of water,v ice or snow.

The small amount of ice that'may form in this space readily may be broken to remove the cap'.4
